When you place a <label> inside the template of a panelbar, and click on that label, the select event fires twice instead of the expected once.

Note: works as expected on collapsible items, only items without children exhibit the problem.

Reproduction of the problem
reproducible: https://dojo.telerik.com/OXazIKUq

Expected/desired behavior
the event keeps firing only once as if you clicked on any place in the item outside of the label.
